Abstract

In the present invention, a method is proposed for obtaining a sol or suspension, said method comprising: providing a solid-particle aerosol; providing an aerosol of particles formed by a fluid medium; bringing the solid-particle aerosol into contact with the aerosol of particles formed by the fluid medium so as to be obtain an aerosol of sol or suspension particles, wherein in the sol or suspension particles solid particles are suspended in particles of the fluid medium; and precipitating the aerosol of sol or suspension particles so as to obtain macroscopic (large) quantities of sol or suspension. The proposed method makes it possible to obtain stable sols and suspensions with a minimal degree of defectiveness and fragmentation of solid particles and with a minimal degree of solid particle agglomeration in less time. Also proposed are sols and suspensions obtained using the present method, and the use of the present method for removing suspended particles from air.
